Recognizing and identifying human locomotion is a critical step to ensuring fluent control of wearable robots, such as transtibial prostheses. In particular, classifying the locomotion mode and estimating the gait phase are key. In this work, a novel, interpretable, and computationally efficient alg
For robotic transtibial prosthesis control, the global tibia kinematics can be used to monitor gait cycle progression and command smooth and continuous actuation. In this work, these global tibia kinematics define a phase variable impedance controller (PVIC), which is implemented as the nonvolitiona…
Powered lower-limb prostheses have shown promise in helping individuals with amputation regain functionality that passive prostheses cannot provide. However, the best method for controlling these devices in coordination with their users is still an open research topic. While powered devices can repl…
Phase variable control based on global tibia kinematics holds promise for predicting gait cycle progression to continuously control robotic transtibial prostheses. Calibration of the phase variable is critical to ensure its monotonic behavior, to approach a linear relationship with gait percentage,…
Realizing the potential of active lower-limb pros-theses to increase user mobility and efficiency requires safe, reliable, stable, and intuitive control strategies. The two prevailing classes of lower-limb prosthesis control can be categorized as volitional and non-volitional. Volitional control str…
